Recent studies show a relationship between symptoms of Attention-deficit/Hyperactivity Disorder(ADHD) during childhood and subsequent psychotic disorders. Moreover the first episode of psychosis(FEP) is typically preceded by a prodrome with deficits in attention. There are only 2 previous studies in FEP that evaluate the presence of ADHD in these patients and their impact on clinical presentation. The objective of our study is to examine the prevalence of ADHD in a sample of 130 patients with an incipient psychotic(IP) disorder, treated at the Early Intervention Service of Reus, aged between 14 and 28. The Structured Diagnostic Interview of ADHD in adults(DIVA) was administered. The data were analyzed using SPSS version 20,0 for Windows. Sample consisted in 97 FEP and 33 ARMS. Mean age of sample was 24,36, 63,84% were men and 37,39% of subjects met criteria for ADHD. In the FEP subgroup 32,97% fulfills diagnostic criteria for ADHD (versus 51.72% in ARMS, 51,72% of men), 90,32% of men.There was a greater prevalence of ADHD in the ARMS sample compared with FEP. Those with childhood ADHD, showed significantly higher rates of cannabis use and greater prevalence of neurodevelopmental delay compared with patients without ADHD. The FEP-ADHD group scored significantly higher in the positive and negative scales of Positive and Negative Syndrome Scale compared with the FEP-alone. Our 37,39% prevalence rate of childhood ADHD in FEP and ARMS was in the higher range of that reported in previous studies. This suggests the necessity of further studies to clarify the association between all of them.
